NASA is currently formulating a mission to explore Europa and investigate the moon's potential habitability. The mission would send a highly capable, radiation-tolerant spacecraft into a long, looping orbit around Jupiter to perform repeated close flybys of Europa. During these flybys, the mission would take high-resolution images; determine the composition of the icy moon's surface and faint atmosphere; and investigate its ice shell, ocean and interior.

If we find life out in the Solar System in my lifetime, I'd bet the farm on Europa being the site of the find.
